Hi, Is your application named HelloServlet also? If so, I suggest changing its name to reduce confusion. Call it "myApp" or whatever you want.
Next, correct the actual code of your servlet. Having an empty service() method means your servlet will do nothing. Take out that method completely so that the parent class' service method is used. I also suggest putting your servlet in a package, e.g. com.mycompany.HelloServlet. Modify web.xml accordingly, specifically the <servlet-class> element. Take out the trailing slash from the url-pattern element of the servlet-mapping. Take out the leading slash from the /index.jsp welcome-file. These two changes are not strictly needed but are better style. Then restart tomcat. You should be able to access your servlet at http://yourhost:yourport/myApp/HelloServlet. And if you haven't done so already, make sure to read http://jakarta.apache.org/tomcat/tomcat-5.0-doc/appdev/index.html.
